Hi list, i'm trying to study fft in Pd and still don't understand the numbers produced by the analysis. I'm on Pd "vanilla" 0-40.2 in debian. I just patch this:
[float]
|
|
[osc~]
|
| [bang]
| /
[rfft~] / |
\ \ |
\ / \ |
\ / [print~ imaginary]
[print~ real]
and then type "0" and "1" in float box and this analysis came to terminal:
